Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

53BP1 expression is a modifier of the prognostic value of lymph node ratio and CA 19–9 in pancreatic adenocarcinoma [PDF]

open access: yes, 2013
BACKGROUND: 53BP1 binds to the tumor suppressor p53 and has a key role in DNA damage response and repair. Low 53BP1 expression has been associated with decreased survival in breast cancer and has been shown to interact with several prognostic factors in ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Value of Ca 19-9 Assay in Serum and Duodenal Juice in the Differential Diagnosis of Pancreatic Disease

open access: yesThe International Journal of Biological Markers, 1987
Levels of CA 19-9 in the serum and duodenal juice of nine patients with pancreatic adenocarcinoma (PC), ten patients with chronic calcifying pancreatitis (CCP) and ten healthy volunteers (C) were determined by immunoassay.

Biochemical markers in cancer of the ovary : a review [PDF]

open access: yes, 1990
The ideal tumour marker would be one which is detectable before obvious clinical involvement. A number of biochemical markers have been used to diagnose carcinoma of the ovary.

Two Lane Traffic Simulations using Cellular Automata

open access: yes, 1995
We examine a simple two lane cellular automaton based upon the single lane CA introduced by Nagel and Schreckenberg. We point out important parameters defining the shape of the fundamental diagram.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

The Reliability of Highly Elevated CA 19‐9 Levels [PDF]

open access: yesDisease Markers, 1993
CA 19‐9 is used as a tumour marker of the upper gastrointestinal tract. However, extremely elevated CA 19‐9 levels are found also in patients with benign diseases. Cholestasis was present in 97.1 % of patients with high elevated CA 19‐9, independent of their primary disease.

The multi-faceted Type II-L supernova 2014G from pre-maximum to nebular phase [PDF]

open access: yes, 2016
We present multi-band ultraviolet, optical, and near-infrared photometry, along with visual-wavelength spectroscopy, of supernova (SN) 2014G in the nearby galaxy NGC 3448 (25 Mpc). The early-phase spectra show strong emission lines of the high ionisation

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.
